Previous Customer Questions For Sennheiser HMEC-25-KAP-2 ANR Headset: Ask Your Own Question

On Sunday, January 13, 2008 a customer asked: Q: Which headset works best for the 737-800? A: The 737 can get pretty loud in the cockpit so I would stay with an earcup design as opposed to the flat ear seals (on the Sennheiser HMEC46 for example). Personally, I would go with the Sennheiser HMEC-25-KA (or HMEC-25-KAS if you want stereo and dual volume controls) or the Telex 850/.
